## Summary description

EK-Quantum Torque 6-Pack fittings by EK Water Blocks are brass, black fittings for liquid cooling loops. Each fitting has a height of 19 mm and is designed for tubing with a 4.5 mm outer diameter. Suitable for compact custom cooling builds, they provide secure connections between tubes and components and ensure reliable coolant flow in PC water-cooling systems.

## Long description

EK-Quantum Torque 6-Pack STC 12/16 contains six EK-Torque STC compression fittings for 12/16 mm (ID/OD) soft tubing. These fittings are made of CNC-machined brass with a satin black finish on the barb and compression rings, and use rubber O‑rings for sealing. They are compatible with common flexible tubes such as PVC, EPDM, Norprene and silicone. The design includes a compression locking ring that compresses the tubing wall to prevent it from being pulled off the barb, plus external grooves for easier hand tightening. Colored aesthetic rings can be added (sold separately) to personalize the look.
Advantages
The fittings provide a secure, compression-style connection for soft tubing without requiring clamps. CNC-machined brass construction and a satin black finish offer durability and a uniform appearance. The compression ring design improves grip on tubing while external grooves help with manual tightening. Interchangeable aesthetic rings allow visual customization to match other EK-Quantum components.
Suitable for
Soft tubing connections in PC liquid cooling loops
Systems using 12/16 mm (ID/OD) flexible tubing
Builds where a consistent satin black appearance is desired

Pack contents: 6 fittings

How to use
Push the soft tube onto the fitting barb until it seats fully, then screw down the compression locking ring to compress the tubing wall and secure the connection. Hand-tighten using the external grooves on the ring; ensure the O‑ring is in place and correctly seated before final assembly. For aesthetic customization, screw an interchangeable colored ring onto the fitting before installing the compression ring (colored rings sold separately).
Usage recommendations
Verify tube inner and outer diameters match the 12/16 mm specification and inspect O‑rings for damage before installation. Do not overtighten the compression ring—tighten by hand until secure. Use only compatible flexible tubing materials and replace O‑rings periodically to maintain a reliable seal.
